Stroll around the city, say (4)
I believe the answer is:
roam
'stroll' is the definition.
(I've seen this in another clue)
'around the city say' is the wordplay.
I cannot quite see how this works, but
'around' could be 'o' (a round letter) and 'o' is located in the answer.
The remaining letters 'ram' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for roam that I've seen before include "Meander" , "Travel widely" , "Prowl" , "Travel aimlessly" , "go on walkabout" .)
